In some cases I find it useful to apply MORE solder prior to desoldering.
It seems wrong but the solder help conduct heat to the pins where it is needed. Solder is a much better conductor of heat then the board itself. The additional solder may prevent the board from cooking.

Nigel Goodwin said:Perfectly standard procedure, I almost always use it, it's particularly good for lead-free solder, apply extra leaded solder and it comes off MUCH easier.
